Application filed October 24 1901. berial No. 79,809. (No model.)

To a, whom, it may concern.-

Be it known that I, HENRY S. BREWINGTON, a citizen of the United States,residing in the city of Baltimore, in the State of Maryland, haveinvented certain new and useful Improvements in Bottle-Stoppers, ofwhich the following is a specification.

This invention relates to bottle-stoppers of that class in which asheet-metal cap and a suitable packing placed in the same is appliedover the mouth of the bottle, the object of the invention being tosupply a cheap sealing device or closure forbottlcs by which the bottlescan be hermetically sealed, so as to prevent the escape of gas from thebottle, and which can be attached to the bottle in a quick andconvenient manner and removed from the same by one of the Well-knownbottle-openers; and for this purpose the invention consists of abottle-stoppercomprisinga cap provided with an external circumferentialcorrugation or groove and forming an internal annular bead or shoulderbelow its top, a packing-disk placed in said cap and retained by saidbead, and a depending cylindrical portion below said bead, saidcylindrical portion being adapted to be applied to an annular exteriorshoulder on the neck of the bottle, as will be fully describedhereinafter and finally pointed out in the claims.

In the accompanying drawings, Figure 1 represents a perspective view ofa cup-shaped blank used for the caps of my improved botole-stopper. Fig.2 is a vertical central section of the same. Fig. 3 is a perspectiveview of the cap provided with a circumferential corrugation forretaining the packing-disk in the same. Fig. 4; is a vertical centralsection of Fig. 3. Figs. 5 and 6 are vertical transverse sectionsshowing my improved stopper,

respectively, as placed in position over the bottle-neck and after beingapplied to the same; and Fig. 7 is a side elevation of my improvedbottle-stopper shown in position on the bottle-neck.

Similar letters of reference indicate corresponding parts in thedifferent figures of the drawings.

Referring to the drawings, a represents the neck of a bottle, which isprovided with an annular exterior shoulder or rim (1, a groove 1) belowsaid shoulder or rim, and a larger bulge 1) below the groove, as shownclearly in Figs. 5 and 6.

The stopper consists of a cap (I, of suitable sheet metal, the blank dof which is madein the shape ofan inverted cup, as shown in Figs. 1 and2. Into the cup-shaped blank d is inserted a packing-disk e, of cork orother suitable elastic material. The packing-disk e is made cylindricalin shape and retained in the cup-shaped blank (1 by pressing an externalcircumferential corrugation, forming an internal annular head (1 at ashort distance from the top of the blank, into the same, said beadretaining the packing-disk e by compressing the circumference of thesame, so as to prevent thereby the dropping or detaching of thepacking-disk from the cap before it is applied to the bottle. Below thebead d a depending cylindrical portion (1 is formed in the cap, Whichserves for the purpose of attaching the same to the annular exteriorshoulder or rim (1' on the bottle-neck. This is accomplished by placingthe cap with the packing-disk over the mouth of the bottle in such amanner that the circumferential corrugation or bead, together with thepacking-disk, rest on the top of the bottle-neck, as shown in Fig. 5.When the cap and packing-disk are in this position, the dependingcylindrical portion of the cap is attached to the annular exteriorshoulder or rim on the bottle-neck by inwardly compressing its loweredge, so as to produce a tight fit on the lower part of the rim, asshown in Fig. 6. Simultaneously a downward pressure is exerted on thetop of the cap, so that the thickness of the upper portion above thebead and the thickness of the packing-disk in the same is reduced, thelower surface of the packingdisk tightly applied to the top of thebottleneck, While the under side of the packingdisk projects somewhatinto the mouth of the bottle. By the tight application of thepacking-disk to the top of the neck of the bottle the hermetical sealingof the bottle is obtained by the tight compression of the packing-disk,so that the liquid in the bottle is prevented from passing through oraround the disk and corroding the inner surface of the cap. When the capis thus applied to the bottle-neck, it has a neat appearance from theoutside, as there are no projecting edges 2 I n, I

of any kind which can catch, so as to produce the accidental removal ofthe cap from the bottle. 7

Any-approved bottle-opener can be used for opening my improvedbottle-stopper by engaging the inwardly compressed or spun lower edge ofthe cap, said lower edge giving a sufficient hold to the bottle-openerfor being readily removed whenever the bottle is to be opened.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. The combination, with a bottle-neck provided withan exterior annular shoulder at its edge and a groove below the same, ofa sealing-cap having an external circumferential corrugation which formsan interior annular bead, and having a depending cylindrical portionbelow said head adapted to fit around said exterior annular shoulder ofthe bottle-neck, and its lower edge compressed into said groove, and apacking-disk retained in the upper portion of the cap above saidinternal head, the upper and lower walls of the corrugation beingseparated when'the cap is affixed to the bottle, substantially as setforth.

2. The combination, with a bottle-neck provided with an exterior annularshoulder, of a sealing-cap having an external annular corrugationforming an internal annular bead and also having a depending cylindricalportion below said bead compressed inwardly below the shoulder of thebottle, and a packing-disk retained in the upper portion of the capabove the bead, the upper and lower walls of the corrugation beingseparated when the cap is affixed to the bottle, substantially as setforth.

In testimony that I claim the foregoing as my invention I have signed myname in presence of two subscribing witnesses.

HENRY S. BREWINGTON.
